Hello Hossman, Thanks for your help. As I wrote on my previous replies, your suggestion about an invalid UID may explain the error code from IE. But why did it run once, I wonder. Where do I need to have the UID set. Would the web host do that, and where is this set? I have seen a few "+" in the code, which one need to be removed? Thanks again for your input, and sorry about all those questions. pip
